it can also deal with how humans are utilizing true runes at that time. Leknaat has been involved in preventing true runes from being collected into a single arsenal - Gate Rune Wars was to prevent Windy from obtaining the Soul Eater and "dual-wielding" true runes. Leknaat also kidnapped Luc and the True Wind Rune from Harmonia. She also wanted to stop Luc from destroying the True Wind Rune, but was too weak to stop him early on, and I think she was too emotionally torn to get get involved in the Suikoden III wars to assist in stopping Luc (or she was extremely confident he would fail).

Also for Suikdoen V, the Sun Rune was in danger of being misused (to destroy neighboring countries) or further going out of control if the Godwins captured the Dawn Rune (since they already had Twilight and Sun).
